MANSI, Giovanni Domenico
Sacrorum Conciliorum Nova et Amplissima Collectio,
cujus Johannes Dominicus Mansi et post ipsius mortem
Florentius et Venetianus editores ab anno 1758 ad annum 1798
priores triginta unum tomos ediderunt, nunc autem continuatat et absoluta
Earlier Giovanni Domenico Mansi (1692–1769) published only supplement to Labbé, but later published also this new edition of councils called "Sacrorum conciliorum nova et amplissima collectio". It was later continued and it contains also everything, which was published in older collections.
Tomes 1-31 (33-1439 A.D.) of this collection were made by Mansi himself with title: Sacrorum conciliorum nova et amplissima collectio, in qua praeter ea quae P. Labbeus et G. Cossartius et novissime N. Coleti in lucem edidere, ea omnia insuper suis in locis optime disposita exhibentur quae J. D. Mansi evulgavit. Ed. Novissima ab eodem Patre Mansi curata Accedunt etiam notae, et dissertationes quam-plurimae, etc. (Florentiae, Venetiis, 1759-1798).
Tomes 31 suppl.-34 are a later supplement (after Mansi's death) to the above from Labbé (ed. 1728-1733) 1440-1727 A.D.
Tome 35 is a later reproduction of parts of Mansi's "Supplement to Labbé" (6. v., 1748-1753), not included by him in this collection.
Tomes 36-53, "Sacrorum conciliorum nova et amplissima collectio continuata curantibus J.B. Martin et L. Petit." (Parisiis : H. Welter, 1901-1927) contain later synods up to the First Vatican Council (1870 A.D.).
